SubjectRe: pivot_root and initrd kernel panic woes
Boy, what a detailed report!

I never used lilo, but:

"Mapping RAM disk" seems to be missing for 2.4.9-12, so you'll get:

> "VFS: Cannot open root device "ram0" or 01:00
> Please append a correct "root=" boot option
> Kernel panic: VFS: unable to mount root fs on 01:00 "

Check your lilo conf. Include it in your reply.

BTW, don't go for 2.4x, x>10. initrd is broken there and is still unfixed.
